Describe a modern issue or challenge facing US cities.


assistant
One major issue facing US cities today is the rising cost of living. Many cities are becoming increasingly expensive to live in, leading to a widening gulf between the rich and the poor. In addition, the lack of affordable housing has led to increasing homelessness and displacement of low-income individuals and families. The rise in living costs has also led to a lack of well-paying jobs, exacerbating economic inequality and forcing more and more people to rely on assistance programs.
